Recombinant Human CD40L Protein (E. coli) 别名：CD40 Ligand; CD154; TRAP; 重组人CD40L蛋白 (E. coli)

目录号 M31176

CD40 Ligand (CD40L/CD154/TRAP) is a type II transmembrane glycoprotein that belongs to the TNF superfamily. The CD40 ligand stimulates B-cell proliferation and secretion of all immunoglobulin isotypes in the presence of cytokines. Recombinant Human CD40 Ligand is produced by E.coli expression system and the target gene encoding Met113-Leu261 is expressed.

生物活性

CD40 Ligand (CD40L/CD154/TRAP) is a type II transmembrane glycoprotein that belongs to the TNF superfamily. The CD40 ligand stimulates B-cell proliferation and secretion of all immunoglobulin isotypes in the presence of cytokines. CD40 Ligand is a differentiation antigen that is expressed on the surface of T-cells. CD40L has been shown to induce cytokine production and tumoricidal activity in peripheral blood monocytes. It also co-stimulates proliferation of activated T-cells and this is accompanied by the production of IFN-gamma, TNF-alpha, and IL2. Recombinant Human CD40 Ligand is produced by E.coli expression system and the target gene encoding Met113-Leu261 is expressed.

Determined by the dose-dependant stimulation of IL-12 & IL-8 induction by PMB (Peripheral Mononuclear) cells, the ED50 is 5.0-10.0 ng/ml, corresponding to a specific activity of 1.0 x 10⁵ IU/mg.

实验参考

动物实验

建议您制定动物给药及实验方案时，尽量参考已发表的相关实验文献（溶剂种类及配比众多，简单地溶解目的化合物，并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题，未必能保证目的化合物在动物体内充分发挥生物学效用）。
体内实验的工作液，建议您现用现配，当天使用；如在配制过程中出现沉淀、析出现象，可以通过超声和（或）加热的方式助溶。
切勿一次性将产品全部溶解。
